TAPE MOISTENING AND DELIVERY AFPARATUS.

Application filed May 29,

T 0 all whom it may concern:

Be it known that we, lViLLIAM D. ROBERT- sort and STANLEY SAVAGE, citizens of the United States and Great Britain, respectively, residing at Seattle, in the county of. Knig and State of Washington, have in vented certain new and useful Improvements in Tape Moistening and Delivery Apparatus, of which the following is a specification.

This invention relates to an improvement in tape moistening and delivery apparatus wherein a paper tape or the like may have the adhesive covered surface thereof moistened and delivered for convenient use in sealing package wrappers in the usual manner.

As heretofore constructed machines of this type deliver the tape with the forward end thereof unmoistened, due to the fact that the delivery means and moistening means operate uniformly, and the moistening means is compelled to make a partial movement before delivering moistening fluid to the tape. The present invention overcomes this difiiculty by compelling a predetermined action of the'moistening means before initial action of the delivery means, so that the full length of tape delivered is properly moistened.

The invention is'illustrated in the accompanying drawings Figure 1 is a plan of the improved apparatus.

2 is a longitudinal central section, partly in elevation of the same.

Fig. 3 is a' detail in elevation,- illustrating the operatingmeans'for the moistening and delivery rolls.

Fig. 4: is a similar view showing the actuator for the operating means.

Theimproved apparatus comprises a boxlike receptacle 1 having a bottom 2, side walls 3,and an end wall l of less height than the sidewalls. At the end of the re cep'tacle remote from the wall 4 is a cylindrical casing 5 within which on a shaft 6 is supported a reel 7- having a supply of tape 8, preferably paper of a comparatively narrow width. \Vithin the receptacle in advance of the reel 7 is a delivery roll 9 having a friction surface 10, as of sand paper or the like, the roll being mounted upon shaft 11 supported'in the side walls 3. Pivo'tally supported in the side walls 3 at 12 Specification of Letters Patent.

' are arms 13 connected by a cross piece it,

said arms and cross piece forming a frame carrying idle rollers 10 and 16, the former of which overlies and is adapted to coiiperate with the roll 9 for delivery purposes, while the latter guides the tape from the reel to the delivery roll. A spring strip 17 secured to one of the side walls 3 is adapted to bear on the cross bar 1%,to secure the desired pressure.

A liquid container 18 is removably supported upon studs 19 projecting from the side walls-3 of the box 1, said receptacle or container 18 being positioned over the end wall 4. A moistening roll 20'is mounted so as to rotate within the container 18, being supported upon shaft 21 mounted in the side walls 3. The surface of the roller 20 is preferably of non-rusting metal though any appropriate material may be used. The surface of the roller 20 is preferably formed with a slot or groove 23in which operates the free end of a finger 22 secured to the receptacle 1 to prevent the moistened tape from adhering to the surface of the roller.

An important feature of the present in vention resides in the operation ofv the feed roll 9 and the moistening roll 20 by means of a single actuator, the operating means compelling substantially a complete revolution of the moistening roll before the feed or delivery roll is actuated, in order that the initial end of the tape being delivered may be properly moistened. An operating slide 2% is guided in a recess 25 formed in one side wall 3 of the receptacle 1, said slide having elongated openings 26 and 2? to slidably embrace pinions 28 and 29 secured on the ends of theshafts 11 and 21 respectively. Pinion 29 on the noistening roll is smaller than pinion 28 on the delivery roll, and the openings in the slide correspond in dimensions. The upper walls of the respective openings 26, 27. are formed to provide gear racks 30, 31 adapted to cooperate with the respective pinions in the longitudinal movement of the slide, the rack 31 engaging the pinion 29 before the rack 3O engages the pinion 28. An actuator in the form of a hand lever 32 is pivotally supported at 33 and provided with a lateral pin 3% to enter an inclined slot 35 in the slide 2%. A leaf spring 36 in said slot 85 normally holds the slide elevated, so that the racks will not engage the pinions, asfor example in the rearward movement of the slide. As the actuator is depressed the slide is moved. forward, the moisteningroll given substantially a complete revolution beforethe delivery roll is operated, so that the tape 8 when reaching the moistening roll bears upon an already moistened surface of said roll.

Spaced strips 37, 38, are arranged between the delivery and moistening rolls, being secured to the sides 3 of the receptacle 1, the

tape being adapted to pass over the strip 37 n and under the strip 38. The forward edge of the strip 33 is serrated at 39 to provide a tearing edge for the tape,

The operation of the apparatus is apparent from the above description, it being ob-' vious that any desired length of tape may be fed from the reel 7 by suitable successive e. operations of the actuator, andjthat the en tire length oftape so delivered will be of fectivelymoistened. As 18 usual n this type of mach ne thetape employed is of the character having a surface supplied with an ad hesive, which is effective as such when moistened with water. The container 18 will of course containwater for moistening the ad hesive covered side of the tape. lVhat we claim is 1 j r 1.
